FEATURES 03 FEATURES DUAL FUNCTION Intermittent or Continuous SILENT DUAL provides optimum versatility to be programmed as either an intermittent or continuous running fan. Intermittent Mode In intermittent mode the fan starts automatically when it detects a slight increase in humidity. As humidity rises and falls, the motor speed tracks the humidity in direct correlation until the humidity level has fallen below the set threshold, ensuring quiet and efficient operation. For sudden peaks in humidity, the fan operates in boost mode. In intermittent mode, the fan also automatically starts (75% of the maximum speed) when movement is detected and will continue to operate for the set period selected by the adjustable ‘run-on’ timer. Over-run Timer There are two setting available for the over-run timer: 2 minutes (for bathrooms less than 4m 2 ) and 15 minutes (for bathrooms over 4m 2 ). Continuous Mode In continuous running mode, the motor speed operates the same as intermittent, however instead of coming to a complete stop, the fan continues to operate on trickle speed (43% of maximum speed). ZONE 1 5 WA R R A N T Y YEAR DUAL SENSING The SILENT DUAL operates automatically when it detects movement (via the PIR) or rises in humidity levels and activates a pre-set mode to achieve the lowest energy consumption and the lowest noise level. DUAL CONNECTION Direct two-wire connection (L, N) for ease of installation. DUAL INLETS The SILENT DUAL has dual inlets for enhanced aerodynamic performance. Air is directed via the front and side panels, achieving similar performance to a traditional front grille but in a stylish and slim-line design to deliver greater pressure at low flow rates.
